A brief description:
松套伸缩接头 和限位短管等构件组成。 B2F type double flange limit expansion joint is composed of loose sleeve expansion joint and limit short tube and other components. It can prevent the pipeline from leaking or damaging the compensation joint due to excessive displacement. It is mainly used to loosen pipe connections that absorb axial displacement and bear pressure thrust within the allowable displacement range.

Flange limit expansion joints provide protection for pumps, valves and other equipment
Flange limit expansion joints are new products for connecting pumps, valves and other equipment to pipelines. They are connected by full bolts to make them a whole and have a certain amount of displacement, so that during installation and maintenance, according to the site The installation size is adjusted, and the axial thrust can be transmitted to the entire pipeline during work. This will not only improve work efficiency, but also play a protective role against pumps, valves and other equipment.
Flange limit expansion joint description:
1. BY (SSJB-3) type gland type loose sleeve limit expansion joint is suitable for welding on both sides with the pipe. When installing, loosen the gland nut and adjust the short pipe at both ends to the pipe after adjusting the installation length. Tighten the nuts evenly using the diagonal method, and adjust the anti-off nut.
2, AF (VSSJA) flange loose sleeve expansion joint is suitable for one side connection with the flange, while plugging with the pipe, without welding, reasonable structure, reliable seal, fast and convenient installation.
3. AY (SSJB) gland type loose sleeve expansion joint is suitable for both sides to be inserted into the pipe, no welding is required, the structure is reasonable, the seal is reliable, and the installation is fast and convenient.
4, B2F (VSSJA-2) double flange loose sleeve limit expansion joint is suitable for both sides to connect with the flange, adjust the length of the connection between the two ends of the product and the flange during installation, tighten the gland bolts diagonally in turn, and then Adjust the limit nut, so that the pipeline can freely expand and contract within the range of expansion and contraction, lock the expansion and contraction, and ensure the safe operation of the pipeline.
5. BF (VSSJA-1) type single flange loose sleeve limit expansion joint is suitable for connecting to the flange while welding to the pipeline. During installation, adjust the installation length of the two ends of the product and the pipeline or flange. Tighten the gland bolts, and then adjust the limit nut, so that the pipeline can be freely expanded and contracted within the range of expansion and contraction, locking the expansion and contraction, and ensuring the safe operation of the pipeline.
